Thank you, and congratulations on your choice of the Roland PK-25 Pedal Keyboard.
The PK-25 is a pedal keyboard unit which was designed especially for the VK-88/VK-
8. It provides a pedal keyboard, an expression pedal for dynamic volume changes, foot
switches that let you control various functions of the VK-88/VK-8 by foot, and a Hold
pedal to sustain the sound.
Features
●
Twenty five-note pedal keyboard and removable expression pedal
The PK-25 features a twenty five-note pedal keyboard for maximum enjoyment of
organ playing. The built-in expression pedal can be removed from the pedal keyboard
unit to make the unit more compact for transportation.
●
Foot switches for controlling the VK-88/VK-8
Two foot switches are built into the expression pedal. During a performance, you can
switch the settings of the VK-88/VK-8 without removing your foot from the
expression pedal or your hands from the keyboard.
●
Hold pedal
A Hold pedal is provided. You can easily operate for additional expressive
possibilities when playing sustain-type sounds.
●
Single-cable connection to the VK-88
When connecting the PK-25 to the VK-88, the PK cable that is supplied with the VK-88
is the only connection required—no need for MIDI cables, analog cables, or an AC
power adaptor. This makes setup quick and easy.

(Do not drop it!)
..........................................................................................................
• Do not force the unit’s power-supply cord to share
an outlet with an unreasonable number of other
devices. Be especially careful when using
extension cords—the total power used by all
devices you have connected to the extension cord’s
outlet must never exceed the power rating (watts/
amperes) for the extension cord. Excessive loads
can cause the insulation on the cord to heat up and
eventually melt through.
..........................................................................................................
• Before using the unit in a foreign country, consult
with your retailer, the nearest Roland Service
Center, or an authorized Roland distributor, as
listed on the “Information” page.

• Do not put anything that contains water (e.g.,
flower vases) on this unit. Also, avoid the use of
insecticides, perfumes, alcohol, nail polish, spray
cans, etc., near the unit. Swiftly wipe away any
liquid that spills on the unit using a dry, soft cloth.
..........................................................................................................
• Always grasp only the plug or the body of the AC
adaptor when plugging into, or unplugging from,
an outlet or this unit.
..........................................................................................................
• At regular intervals, you should unplug the AC
adaptor and clean it by using a dry cloth to wipe
all dust and other accumulations away from its
prongs. Also, disconnect the power plug from the
power outlet whenever the unit is to remain
unused for an extended period of time. Any
accumulation of dust between the power plug and
the power outlet can result in poor insulation and
lead to fire.
..........................................................................................................
• Try to prevent cords and cables from becoming
entangled. Also, all cords and cables should be
placed so they are out of the reach of children.
..........................................................................................................
• Never climb on top of, nor place heavy objects on
the unit.

Important Notes
In addition to the items listed under “USING THE UNIT SAFELY” on page 2 and 3, please read and observe the following:
Power Supply
• Do not connect this unit to same electrical outlet that is being used by an electrical appliance that is controlled by an inverter
(such as a refrigerator, washing machine, microwave oven, or air conditioner), or that contains a motor. Depending on the
way in which the electrical appliance is used, power supply noise may cause this unit to malfunction or may produce audible
noise. If it is not practical to use a separate electrical outlet, connect a power supply noise filter between this unit and the
electrical outlet.
• The AC adaptor will begin to generate heat after long hours of consecutive use. This is normal, and is not a cause for concern.
• Before connecting this unit to other devices, turn off the power to all units. This will help prevent malfunctions and/or
damage to speakers or other devices.
Placement
• This device may interfere with radio and television reception. Do not use this device in the vicinity of such receivers.
• Do not expose the unit to direct sunlight, place it near devices that radiate heat, leave it inside an enclosed vehicle, or
otherwise subject it to temperature extremes. Also, do not allow lighting devices that normally are used while their light
source is very close to the unit (such as a piano light), or powerful spotlights to shine upon the same area of the unit for
extended periods of time. Excessive heat can deform or discolor the unit.
• To avoid possible breakdown, do not use the unit in a wet area, such as an area exposed to rain or other moisture.
• Do not allow rubber, vinyl, or similar materials to remain on the piano for long periods of time. Such objects can discolor or
otherwise harmfully affect the finish.
• If you slide the PK-25 over the floor, the floor could get scratched. To avoid this, lift the unit as you move it. Make sure to keep
it level, though.
• Do not store the PK-25 on its end, or lean it against a wall for use. It may fall over, causing injury.
355b
• When moved from one location to another where the temperature and/or humidity is very different, water droplets (condensation) may form inside the unit. Damage or malfunction may result if you attempt to use the unit in this condition. Therefore,
before using the unit, you must allow it to stand for several hours, until the condensation has completely evaporated.
358
• Do not allow objects to remain on top of the keyboard. This can be the cause of malfunction, such as keys ceasing to produce
sound.
Maintenance
• To clean the unit, use a dry, soft cloth; or one that is slightly dampened. Try to wipe the entire surface using an equal amount
of strength, moving the cloth along with the grain of the wood. Rubbing too hard in the same area can damage the finish.
• Never use benzine, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation.
Additional Precautions
• Use a reasonable amount of care when using the unit’s buttons, sliders, or other controls; and when using its jacks and
connectors. Rough handling can lead to malfunctions.
• When connecting / disconnecting all cables, grasp the connector itself—never pull on the cable. This way you will avoid
causing shorts, or damage to the cable’s internal elements.
558b
• To avoid disturbing your neighbors, try to keep the unit’s volume at reasonable levels (especially when it is late at night).
• When you need to transport the unit, package it in the box (including padding) that it came in, if possible. Otherwise, you will
need to use equivalent packaging materials.
• When you need to transport the unit, package it in the box (including padding) that it came in, if possible. Otherwise, you will
need to use equivalent packaging materials.
